Anthurium plant named ‘ARAANTRED6’

ABSTRACT

‘ARAANTRED6’ is a new and distinctive variety of Anthurium plant which is characterized by the combination of a moderately fast-growing herbaceous perennial with a broad, upright growth habit, an abundance of inflorescences, held above the floral plane, vibrant red spathes, and the stability of all characteristics from generation to generation. The new variety is typically produced as an indoor ornamental plant.

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Anthurium andraeanum Linden ex Andre.

Variety denomination: The inventive variety of Anthurium disclosed herein has been given the variety denomination ‘ARAANTRED6’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2016/2993, filed Nov. 30, 2016, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The new cultivar is a seedling selection which resulted from the controlled pollination of Anthurium andraeanum ‘K38’ (not patented), the seed parent, and Anthurium andraeanum ‘K20’ (not patented), the pollen parent. Both parents are developed and owned by the inventor and were never commercially released. Said cross was performed by the inventor in De Lier, The Netherlands, in October of 2013. Seeds were harvested from ‘K38’, sown, and grown to maturity in order to evaluate for unique characteristics which may be of commercial value. In February of 2015, after evaluating the seedlings for approximately one year, one progeny was observed to exhibit a relatively fast rate of growth and an abundance of inflorescences with vibrant red spathes. The new cultivar was selected for commercialization and given the breeder denomination ‘ARAANTRED6’.

Asexual Reproduction: Asexual reproduction of ‘ARAANTRED6’, by way of meristematic tissue culture, was first performed in February of 2015 at a laboratory in De Lier, the Netherlands. Three successive generations so produced have shown that the unique features of the instant cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘ARAANTRED6’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Anthurium cultivar ‘ARAANTRED6’. These traits, in combination, distinguish ‘ARAANTRED6’ as a new and distinct cultivar.

-   -   1. Anthurium ‘ARAANTRED6’ is a moderately fast-growing         herbaceous perennial with a broad, upright growth habit; and     -   2. Anthurium ‘ARAANTRED6’ exhibits an abundance of         inflorescences, held above the floral plane; and     -   3. Anthurium ‘ARAANTRED6’ exhibits inflorescences with vibrant         red spathes.

FIG. 3 shows, as nearly true as it is reasonably possible to make the same in color illustrations of this type, the typical inflorescence of ‘ARAANTRED6’.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety of Anthurium known as ‘ARAANTRED6’, based upon observations made from a sample set of plants grown in 17 cm nursery pots which were approximately 40 weeks old from a rooted cutting. Plants were grown in a greenhouse in De Lier, The Netherlands, utilizing conventional greenhouse production protocols for Anthurium, which consisted of regular irrigation by way of ebb and flood watering benches and fertilizer applications of a complete fertilizer with micro nutrients at an electrical conductivity value ranging from 1.0 to 1.8. No chemical pest or disease measures were utilized in production. Young plants are assimilated to the greenhouse under shade cloth and later move to light levels ranging from 3000 to 4000 lux for the final 5 months of production. Observation data was recorded in October of 2017.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘ARAANTRED6’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, sixth edition (2015).
